Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15CKW01-12-EB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Mounting type (Panel Mount, Front)
• Actuator type (Round, Button)
• Voltage rating - AC (125V minimum)
• Voltage rating - DC (30V minimum)
• Operating temperature range (-25°C to 50°C)
• Termination style compatibility

Allowable Variation Parameters:

• Current rating (equal to or greater than 1A)
• Illumination type and color (may differ from incandescent yellow)
• Illumination voltage (alternative nominal voltages acceptable)
• Mechanical and electrical life (equal to or greater than specified)
• Panel cutout diameter (larger diameter acceptable with mechanical redesign consideration)

The substitute part YB15CKW01-5D12-JD meets the mandatory compatibility criteria while offering enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-5D12-JD is functionally equivalent to the KB15CKW01-12-EB for applications requiring SPDT pushbutton switch operation at 125V AC and 30V DC. Both components maintain identical voltage ratings, operating temperature ranges, and circuit configurations. The substitute part carries active product status from NKK Switches, ensuring continued availability and supply chain reliability compared to the obsolete KB15CKW01-12-EB.

Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The YB15CKW01-5D12-JD provides enhanced performance with 3A current capacity versus 1A, extended mechanical life (1,000,000 cycles versus 100,000 cycles), and doubled electrical life (100,000 cycles versus 50,000 cycles).

Design consideration is required for panel cutout diameter: the substitute part requires a 16.00mm circular opening compared to the original 12.30mm specification. Illumination characteristics differ, with the substitute utilizing LED amber illumination at 12 VDC instead of incandescent yellow at 12 VAC. Termination style modification from solder lug to solder with quick connect option may require circuit board redesign.

Frequently Asked Questions (FAQ)

Q: Can YB15CKW01-5D12-JD directly replace KB15CKW01-12-EB without modifications?

A: Electrical substitution is valid for SPDT circuit operation at specified voltage and current ratings. Mechanical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Illumination voltage source must be changed from 12 VAC to 12 VDC, and termination connections require adaptation from solder lug to solder/quick connect configuration.

Q: What are the key compatibility criteria for substitution?

A: The substitute part must maintain SPDT circuit configuration, On-Mom switch function, panel mount front installation, round button actuator type, 125V AC and 30V DC voltage ratings, and -25°C to 50°C operating temperature range. Current rating, illumination type, mechanical life, and electrical life may exceed original specifications.

Q: Is the substitute part suitable for the same application environments?

A: Yes. Both components operate across identical temperature ranges (-25°C to 50°C) and maintain equivalent voltage ratings. The substitute part's enhanced mechanical and electrical life characteristics provide extended service capability in equivalent environments.

Q: What design changes are necessary for panel integration?

A: Panel cutout diameter must be increased from 12.30mm to 16.00mm. Illumination circuit voltage source must be modified from 12 VAC to 12 VDC. Termination connections require redesign to accommodate solder and quick connect terminals instead of solder lug configuration.

Q: Are both components compliant with current regulatory standards?

A: Yes. Both KB15CKW01-12-EB and YB15CKW01-5D12-JD are ROHS3 compliant and REACH unaffected, meeting current electronic component regulatory requirements.
